A DHCP option.
DHCP options consist of a mandatory tag, a length field that is mandatory for all options except DHCP_PAD
and DHCP_END
, and a payload.
uint8_t dhcp_option::len |
Length.
This is the length of the data field (i.e. excluding the tag and length fields). For the two tags DHCP_PAD
and DHCP_END
, the length field is implicitly zero and is also missing, i.e. these DHCP options are only a single byte in length.
